Vidalia onion production requires a significant amount of manual labor since transplanting and harvesting are performed primarily by hand. To measure the impact of possible hand transplanting inconsistencies, an experiment was conducted at the UGA Vidalia Onion and Vegetable Research Center. Properly transplanted seedlings showed the best growth and yield, with the highest leaf count and bulb population. Treatments simulating poor transplanting conditions showed reduced growth, higher mortality rates, and lower yields.
